Crib mattresses are an expensive baby necessity and I wanted to prolong the life of it by preventing wear and tear with a mattress protector. First and foremost my baby’s health and safety are at the top of my list when I’m purchasing any products so I needed something that didn’t contain harmful chemicals. Swaddlez bamboo crib mattress has a waterproof layer made of TPU which doesn’t leach chemicals. The fabric is a quilted layer made of 77% bamboo and 23% polyester. It’s also machine washable for easy clean up. After opening the package I instantly noticed how soft the fabric was. One of the great things about bamboo is that is gets softer and more absorbent after each wash. It didn’t have a chemically odor and is well made. It goes on like a fitted sheet and was a quick and easy to put on. The fit was perfect and snug so it stays put, keeping baby and the mattress safe. It’s a great gift option for an expectant parent or for anyone wanting to limit their child’s exposure to harmful chemicals while ensuring the longevity of their infants crib mattress. I received this product in exchange for my honest review.
